[SOLVED] Do I really need a 750w PSU to power my Powercolor R9 280 ?

[Dimension King]

Hey guys, so as the question says, do I really have to buy a 750w PSU? cuz I was running around google and most of the sites recommends a 750 one, but I also read that it doesn't need a 750 one as long as it is a very high quality PSU (like Corsair, Coolermaster, Seasonic and etc.) so what gives?
here's my GPU for full reference:

Thanks in advance!

oh my bad, anyway here are my PC parts:
I5- 3470 3.2GHz
8gb's of DDR3 RAM
120gb SSD
500gb Western Digital Blue HDD 7200 RPM

also I took in reference of the one you linked, and the Powercolor variant is only 200w. the one you linked may have tested a something like a MSI variant which has 250w.
if there is still missing, feel free to ask, still a noob to this gig and yea first build.
once again thanks!

A good quality 550 watt PSU should be fine for your specs. All brands have models that range from good to poor so you can't go by brand name alone. It depends on what's available where you live or what you can have shipped to you that fits your budget.

Do you now have a psu?
If so, what is the make/model?
Some units rated at 700W can not even deliver 350w where you need it on +12v.
A quality 650W unit should do if you are buying new.
Consider a quality power supply as a good long term investment.
It will be good for many future updates.
A psu will only use the power demanded of it, regardless of the max capability.
Look for a unit with 7 to 10 year warranty.

You might want to consult some quality tier lists such as this:

PSU Tier List [OLD]

Credit to @Starelementpokeand @Energycore for helping out with this long-awaited refresh of the old PSU tier list by Aniallation (who previously went several months without logging in), leaving the old list in need of help. This is simply an update of the list that was flawed in creation by the P...

linustechtips.com

That list is old, there are better ones.

Look up a review from a trusted power supply review site for any psu you are considering.
I don't think any of the units above would be considered as a long term investment.
The seasonic is probably the best, but it is an older design which may not support modern C state motherboards well.

Be prepared to double your budget for a good power supply and buy it once.
A better strategy than buying a cheap psu twice after the first failed and possibly damaged parts.

Here is an example of a seasonic focus 750w unit with a 7 year warranty $110.

Both Corsair and Seasonic make for the most part, very good power supplies. However, both brands have their turds. And you have picked two of their turds.

It's 99% guaranteed that if you go away, pick out two more power supplies, one from each of these brands, you'll come back with one people here can recommend.

Edit: cuz yea also on a budget and seems that the CM is the only option I have that is somewhat high on the tier list, also viewed from sites, mostly positive reviews on it
